(Submitter supplied) Acetyl-CoA is a key intermediate in metabolism situated at the intersection of many metabolic pathways. The reliance of histone acetylation on acetyl-CoA enables gene expression to be coordinated with metabolic state. Previous studies have linked abundant histone acetylation to activation of genes involved in cell growth or tumorigenesis. However, under glucose starvation, the extent to which histone acetylation is important for gene expression remains poorly understood. more...

(Submitter supplied) We found acetyl-CoA levels increase when cells are committed to growth. We also found 3 components of the SAGA complex, Spt7p, Sgf73p and Ada3p as well as histones are dynamically acetylated in tune with the acetyl-CoA levels. ChIP-seq study reveals SAGA and H3K9ac predominantly occupy growth genes at the OX growth phase of the yeast metabolic cycle indicating acetyl-CoA levels may drive growth gene transcription program through acetylation of these proteins.

(Submitter supplied) Histone acetylation and deacetylation are among the principal mechanisms by which chromatin is regulated during transcription, DNA silencing, and DNA repair. We analyzed patterns of genetic interactions uncovered during comprehensive genome-wide analyses in yeast to probe how histone acetyltransferase (HAT) and histone deacetylase (HDAC) protein complexes interact. The genetic interaction data unveil an underappreciated role of HDACs in maintaining cellular viability, and led us to show that deacetylation of the histone variant Htz1p at lysine 14 is mediated by Hda1p. more...

(Submitter supplied) Epigenetic information is able to interact with the cellular environment and therefore it could be especially useful for reprogramming gene expression in response to a physiological perturbation. In fact, genes induced or repressed by osmotic stress undergo significant changes in the levels of various histone modifications, especially the acetylation levels of histone H3. Exposure of yeast to high osmolarity results in the activation of p38-related SAPK, Hog1, which plays a central role in the control of gene expression. more...

(Submitter supplied) We found that lipid-derived acetyl-CoA is a major source of carbon for histone acetylation. Gene expression profiling of octanoate-treated hepatocytes identified a pattern of upregulated lipid metabolic genes, demonstrating a specific transcriptional response to lipid. These studies expand the landscape of nutrient sensing and uncover how lipids and metabolism are integrated by epigenetic events that control gene expression.

(Submitter supplied) The SAGA complex of Saccharomyces cerevisiae contains greater than 20 components that acetylate and deubiquitylate nucleosomal histones. Its acetyltransferase, Gcn5 preferentially acetylates histones H3 and H2B and is regulated through interactions with Ada2 and Ngg1/Ada3. The N-terminal region of Ada2 contains a SANT domain that contacts Gcn5 near its catalytic site. Sequence alignments of Ada2 homologues indicate a conserved ~120 amino acid residue central region that interacts with Ngg1.To examine the function of this central region, we constructed ada2 alleles with mutations of clustered conserved residues. more...
